Pseudo-Jerome
Catena Aurea · Markusevangelium 11
And when they came nigh to Jerusalem, unto Bethphage and Bethany, at the mount of Olives, he sendeth forth two of his disciples, And saith unto them, Go your way into the village over against you: and as soon as ye be entered into it, ye shall find a colt tied, whereon never man sat; loose him, and bring him. And if any man say unto you, Why do ye this? say ye that the Lord hath need of him; and straightway he will send him hither. And they went their way, and found the colt tied by the door without in a place where two ways met; and they loose him. And certain of them that stood there said unto them, What do ye, loosing the colt? And they said unto them even as Jesus had commanded: and they let them go. And they brought the colt to Jesus, and cast their garments on him; and he sat upon him. And many spread their garments in the way: and others cut down branches off the trees, and strawed them in the way. And they that went before, and they that followed, cried, saying, Hosanna; Blessed is he that cometh in the name of the Lord: Blessed be the kingdom of our father David, that cometh in the name of the Lord: Hosanna in the highest.
Or else, they put upon it their garments, that is, they bring to them the first robe of immortality by the Sacrament of Baptism. And Jesus sat upon it, that is, began to reign in them, so that sin should not reign in their wanton flesh, but righteousness, and peace, and joy in the Holy Ghost. Again, many spread their garments in the way, under the feet of the foal of the ass. What are feet, but those who carry, and the least esteemed, whom the Apostle has set to judge? (v. 1 Cor. 6:4.) And these too, though they are not the back on which the Lord sat, yet are instructed by John with the soldiers.
